I have get the docker of orin drive os sdk 6.0.8.1, and compiling the kernel (kernel 5.15) follow the step:

Compiling the Kernel (Kernel 5.15) | NVIDIA Docs

There were error when I Execute Build-FS with the preceding configuration to rebuild the filesystem as follow:

there was no /drive/drive-linux/kernel/preempt_rt/modules/5.15.98-rt-tegra/extra/nvgpu.ko in the build modules, I can’t find the nvgpu.ko in anywhere, did the nvgpu.ko need build through other patch?

apart form this error , the modules file int he following directory cannot be found as well:

/drive/drive-linux/kernel/preempt_rt/modules/5.15.98-rt-tegra/updates/dkms the dkms directory also can’t be found in the build modules , did the dkms also need to build by other?

thanks

Dear @yuxm1,
Could you check Inaccuracies in steps to build 5.15 kernel module - #5 by SivaRamaKrishnaNV if it helps?

[yuxm1]

Thansk for your replay!
I checked the post and followed the steps ,copy the update directory and other ko like nvgpu.ko to the $NV_WORKSPACE/drive-linux/kernel/preempt_rt${PROD_SUFFIX}/modules/5.15.98-rt-tegra/
,it can get the filesystem success
but I have two question:

1. what is the nvgpu.ko compiled from? can I compiled this module?
2. where is the module file in the update directory get from? can I compiled these module self?

@yuxm1

what is the nvgpu.ko compiled from? can I compiled this module?

No. These are related to nvgpu driver.

@yuxm1

where is the module file in the update directory get from? can I compiled these module self?

I did not get it which module file. Can you elaborate ?

[yuxm1]

@SivaRamaKrishnaNV

elaborate

please look the follow picture:

there was no update/dkms in my built modules which was in the original modules

Dear @yuxm1,
built modules will not have updates folder. The 5.15.98-rt-tegra/updates folder also need to be copied from back up as shown in Inaccuracies in steps to build 5.15 kernel module - #5 by SivaRamaKrishnaNV
